Public Member Functions
void	ChangeClassProperty (string cssProperty, Css.Value newValue)
	This is called to change a property defined by a css selector that matches the class of this element. The request may be rejected if an ID selector or a style attribute on the element overrides this change. More...

void	ChangeClassProperty (CssProperty property, Css.Value newValue)
	This is called to change a property defined by a css selector that matches the class of this element. The request may be rejected if an ID selector or a style attribute on the element overrides this change. More...

Css.Value	GetClassStyle (CssProperty property)
	Gets the CSS property value defined by the class selector for the given property. More...

Css.Value	GetClassStyle (string property)
	Gets the CSS property value defined by the class selector for the given property. More...

void	ChangeIDProperty (string cssProperty, Css.Value newValue)
	This is called to change a property defined by a css selector that matches the ID of this element. This change may be rejected if a style attribute on the element overrides this change. More...

void	ChangeIDProperty (CssProperty property, Css.Value newValue)
	This is called to change a property defined by a css selector that matches the ID of this element. This change may be rejected if a style attribute on the element overrides this change. More...

Css.Value	GetIDStyle (CssProperty property)
	Gets the CSS property value defined by the ID selector for the given property. More...

Css.Value	GetIDStyle (string property)
	Gets the CSS property value defined by the ID selector for the given property. More...

void	ChangeTagProperty (CssProperty property, Css.Value newValue)
	This is called to change a property defined by a css selector that matches the tag of this element. The request may be rejected if a class selector, ID selector or a style attribute on the element overrides this change. More...

void	ChangeTagProperty (string cssProperty, Css.Value newValue)
	This is called to change a property defined by a css selector that matches the tag of this element. The request may be rejected if a class selector, ID selector or a style attribute on the element overrides this change. More...

	ComputedStyle (Element element)
	Creates a new computed style for the given element. More...

bool	Contains (int x, int y)
	Checks if this element's box contains the given co-ordinates. More...

bool	TransformedOverlap (ComputedStyle style)

void	VisibilityNone ()

void	DisplayNone ()

bool	BoxOverlap (ComputedStyle style)

float	GetMidpointX ()
	Gets the position of the midpoint on the x axis. More...

float	GetMidpointY ()
	Gets the position of the midpoint on the y axis. More...

	How much of this elements horizontal content is currently visible? Used by scrolling. More...

float	VisiblePercentageY ()
	How much of this elements vertical content is currently visible? Used by scrolling. More...

bool	Hover ()
	Called when the mouse is now over this element. Internally, it simply tacks :hover onto all the selectors this tag uses and reloads, but only if the :hover selector exists. More...

void	Unhover ()
	Called when the mouse is no longer over this element. This essentially reverses PowerUI.ComputedStyle.Hover. More...

bool	SetModifier (string modifier)
	Applies the given CSS modifier (e.g. "hover") to this element. Note: Modifier order matters! More...

void	UnsetModifier (string modifier)
	Unapplies the given CSS modifier (e.g. "hover") to this element. More...

bool	HasModifier (string modifier)
	Is the named modifier in use on this style? More...

void	RefreshSelector (SelectorType type)
	Makes this element refetch the style of the given selector. E.g. This is called if an element is loaded before the style tag is. The body element is currently the only one this occurs with. When the style loads, it tells the body tag to refresh itself with this method. More...

bool	RemoveStyle (string selector, SelectorType type)
	Removes the given style from this computed style. More...

bool	AddStyle (string selector, SelectorType type)
	Adds the given style from this computed style as a style of the given type. More...

	Sets a css selector that will apply to this element (e.g. it's class or id). More...

void	ChangeParentProperty (CssProperty property, Css.Value newValue)
	Called when a parent object changes its properties. This applies the value only if this element wants to 'inherit' the property. More...

Css.Value	GetLocalStyle (string property)
	Gets the CSS property value defined by the style="" attribute for the given property. Fully resolved properties only. More...

Css.Value	GetLocalStyle (CssProperty property)
	Gets the CSS property value defined by the style="" attribute for the given property. More...

void	ChangeProperty (CssProperty property, Css.Value newValue)
	This is called to change the named property on this element. More...

void	EnforceNoInline ()
	Inline elements with border/bg colour/bg image should split the properties across multiple lines. This looks pretty ugly and is complex enough that it is instead replaced with enforcing inline-block in this situation. This method enforces inline-block if it's required. More...

bool	SetupTransform (Css.Value newValue)
	Sets up the PowerUI.ComputedStyle.Transform object if one is needed. More...

void	ResetScrollbars ()
	Resets the scrollbar elements for this element. More...

void	SetSize ()
	Recalculates the pixel width/height and style offsets. More...

void	RequestTransform ()
	Requests that this element and all it's kids are retransformed. Transforming is a post process, so this is like calling for a paint. More...

void	RequestLayout ()
	Requests that the renderer performs a layout on the next update. Note that layouts are more expensive than a paint. Paints simply update vertex colours and uvs where as layouts rebuild the whole mesh. More...

void	SetParentDimension (int dimension, bool isWidth, ComputedStyle parent)
	Called when either height or width of the parent element changes. This is used to convert % into actual pixels and may recurse to it's children. More...

void	Repaint ()
	Repaints this element at OffsetLeft/OffsetTop with the given PixelWidth and PixelHeight values. A paint is less intensive than a layout as it only updates the uv/vert colours of the mesh. More...

void	WentOffScreen ()

void	Render ()
	Draws this at OffsetLeft/OffsetTop with the given PixelWidth and PixelHeight values. More...

ShaderData	RequireShading ()
	Requires a shading data block on this computed style. More...
